BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla sanderi and hereinafter referred to by the name ‘Lanoregon’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Malause, France. The objective of the breeding program is to create new compact Mandevilla plants with dark red purple-colored flowers.

The new Mandevilla plant originated from a cross-pollination conducted by the Inventor in Malause, France on Sep. 22, 2006 of a proprietary selection of Mandevilla sanderi identified as code number 05-075-22, not patented, as the female, or seed parent with Mandevilla sanderi ‘Rosea Foncé’, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Malause, France in May, 2008.

Asexual reproduction of the new Mandevilla plant by cuttings in a controlled greenhouse environment in Malause, France, since May, 2010 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lanoregon’. These characteristics in combination distinguish ‘Lanoregon’ as a new and distinct Mandevilla plant:

-   -   1. Compact and bushy plant habit.     -   2. Moderately vigorous growth habit.     -   3. Glossy dark green-colored leaves.     -   4. Early flowering habit.     -   5. Dark red purple-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla and the female parent selection         differ in leaf shape and color.     -   2. Plants of the new Mandevilla flower earlier than plants of         the female parent selection.     -   3. Flowers of plants of the new Mandevilla are star-shaped         whereas flowers of plants of the female parent selection are         round in shape.

Plants of the new Mandevilla can be compared to plants of the male parent, ‘Rosea Foncé’. Plants of the new Mandevilla differ primarily from plants of ‘Rosea Foncé’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more freely branching and         bushier than plants of ‘Rosea Foncé’.     -   2. Plants of the new Mandevilla flower earlier than plants of         ‘Rosea Foncé’.     -   3. Flowers of plants of the new Mandevilla are darker in color         than flowers of plants of ‘Rosea Foncé’.

Plants of the new Mandevilla can be compared to plants of Mandevilla sanderi ‘Lannebraska’, disclosed in a U.S. Plant Pat. No. 23,673. Plants of the new Mandevilla differ primarily from plants of ‘Lannebraska’ in flower color as plants of the new Mandevilla have darker red purple-colored flowers than plants of ‘Lannebraska’.

Plants of the new Mandevilla can also be compared to plants of selections of Mandevilla sanderi known to the Inventor, not patented. In side-by-side comparisons conducted in Malause, France, plants of the new Mandevilla differed from plants of selections of Mandevilla sanderi known to the Inventor in the following characteristics:

-   -   1. Plants of the new Mandevilla were more freely branching than         plants of selections of Mandevilla sanderi known to the         Inventor.     -   2. Plants of the new Mandevilla had smaller leaves than plants         of selections of Mandevilla sanderi known to the Inventor.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in two-liter containers in polyethylene-covered greenhouse in Malause, France and under cultural practices typical of Mandevilla commercial production. During the production of the plants, day temperatures ranged from 8° C. to 26° C. and night temperatures ranged from 3° C. to 15° C. Plants were six months old when the photographs and description were taken.
